4 Claims.

This invention relates to vehicle seats and more particularly to anadjustable vehicle seat.

An'object of this invention is to provide in a seat structure meanswhereby the height of the seat, particularly the rear portion thereofmay be adjusted at will, so that the seat may be made comfortable fordifferent persons.

Another object of this invention is to provide an improved basestructure which may be incorporated in a longitudinally adjustable basestructure whereby' the conventional upholstered seat may be secured to aportion of the base structure and made vertically adjustable,particularly at the rear thereof.

The above and various other objects and advantages of this inventionWill in part be described in, and in part be understood from thefollowing detail description of the present preferred embodiment, thesame being illustrated in the accompanying drawing wherein:-

Figure 1 is a perspective view of a base structure for a seatconstructed according to an embodiment of this invention, showing aportion of the conventional seat structure in section.

Figure 2 is a sectional view taken on the line 2 2 of Figure 1.

Referring to the drawing wherein like numerals of reference designatecorresponding parts throughout the several views, the numeral Idesignates generally a hollow base structure comprising a top plate Il,side Walls I2 and end walls I3, constituting dependent flanges securedto the top II. This base I0 is preferably of substantially rectangularconfiguration but, of course, it will be understood that theconfiguration of the base may be varied to suit the style of the seatwith which this base I0 is combined.

In order to provide a means whereby the seat S may be verticallyadjusted, particularly at the rear portion thereof, I have provided anadjustable frame, generally designated as I4, which is provided withoffset forward end portions I5 engaging in slots I6 provided in the topI I adjacent the front or forward edge thereof. In the present instance,this frame member I4 is constructed of substantially U-shapedconfiguration with the parallel legs II thereof having the offsetportions I5 and the bight or rear portion I8 of the frame member I4 isprovided with a plurality of dependent or downwardly extending plates I9provided with a plurality of spaced apart holes I9. The plates 20 extendthrough slots or openings 2| provided in the top II adjacent the rearportion thereof and preferably, the side walls or flanges I2 and the endwalls or flanges I3 are of a height suicient to permit the plates I9 toextend substantially for their full length into the hollow basestructure I0.

An elongated adjusting .bar or rod 22 is adapted to bedisposed inselected alined holes in the 5 plates I9, and the rod 22 will thenengage the top II so as to prevent further downward movement'of theplates I9 and thus maintain the' rear portion of the frame member I 4inraised position. The rod 22 lis provided with a knob 23 at l0 one endwhichis'adapted to extend partially through a hole 24 provided in a sidemember or bracing piece 25 which braces the back B, shown in dottedlines in Figure 2.

It will be understood that the base I 0 may have 15 associated therewithlongitudinal adjusting means so as to adjust the base with respect tothe floor of the vehicle to move the base forward or rearwardly of thepedals. Through the medium of the vertical adjusting means herein- 20before described, the rear portion of the seat can be raised to thedesired degree so as to raise the entire seat S, particularly at therear thereof and thus make it possible for persons of varying heights toconveniently look over the forward 25 portion of the vehicle for drivingor other purposes.

In the use of this adjustable means for a vehicle seat, the seatstructure S may be attached by any suitable means to the frame member I4and the base II may be fastened to the floor of the vehicle or securedto the usual longitudinal adjusting means for a seat. The offsetportions I5 of the frame member I4 may be passed through the slots IBand in this manner the seat S is removably secured to the base I0 withthe offset portions I5 acting as fulcrums or pivots for the seat S.

The rear portion of the seat S may be raised to the desired degree, therod 22 being rst pulled out through the hole 24 in the side member 25.When the rear portion of the seat S has been raised to the desireddegree, the rod 22 is slipped back through the hole 24 and through thealined holes 20 disposed closest to the top II. The rod 22 will thenprevent further down movement of the rear portion of the frame I4 andlikewise the rear portion of the seat S so that the height of the seat Smay be adjusted to the convenience of the person driving the vehicle andthis adjustment will also have the effect of throwing the body of thedriver forwardly in addition to raising the body of the person so thatthe driver can more readily look over the dash or hood of the vehicle.

I claim:- 1. In a Vehicle seat structure, a hollow base,

having a pair of slots in the top thereof, a frame member on the top,offset slot engaging portions 5 carried by the frame, a plurality ofapertured plates secured to the frame member on the side opposite fromsaid slot engaging portions, and a frame adjusting bar engageable inselected alined openings in said plates and in rigid engagement with aportion of said base.

2. In a vehicle seat structure, a hollow base provided with a flat top,said top h-aving a pair of slots adjacent the forward portion thereofand a plurality of spaced apart openings adjacent the rear thereof, aframe member on the top, a pair of offset slot engaging portions carriedby the frame at the forward edge portion thereof and providing meanswhereby the rear portion of the frame may be rocked, a plurality ofapertured plates secured to the underside of the frame adjacent the rearthereof and loosely engaging in the openings in the top and a barextending through selected alined openings in the plates and engagingthe top to hol-d the rear portion of the frame in vertically adjustedposition.

\ 3. A means for adjusting a seat comprising a hollow base having a topprovided with slots adjacent the front portion thereof and also providedwith a plurality of spaced apart openings adjacent the rear portionthereof, a frame member, slot engaging portions carried by the frontportion of the frame member to rockably and detachably secure the framemember to the base, a plurality of dependent apertured plates secured tothe frame member adjacent the rear thereof and loosely eng-aging in theopenings in the top and a frame adjusting bar disposed in selectedalined openings in the plates and engaging the top to hold the rearportion of the frame in vertically adjusted position.

4. A means for vertically adjusting a vehicle seat comprising a hollowbase provided with a pair of openings adjacent the forward edge thereofand with -a plurality of alined spaced apart openings adjacent the rearthereof, a U- shaped frame member, offset portions carried by the freeends of the parallel legs of the U-shaped frame and engaging in saidpair of openings in the forward portion of the top, a plurality ofdependent apertured plates secured to the underside of the bight of theframe and loosely engaging in said spaced apart openings and a frameadjusting bar extending through selected alined openings in the platesand engageable with the top of the base to hold said plates againstdownward movement and thereby hold the rear portion of the frame invertically adjusted position with respect to the forward end.
